You’ve finally hopped on the Basal Body Temp (BBT)-train and are ready to track your cycle with way more accuracy than just by looking at the calendar each month.
But now you’re wondering if you’re placing your basal body thermometer in the right spot!
Because yes, 𝒘𝒉𝒆𝒓𝒆 you place your BBT thermometer matters! Researchers found a 0.3-degree difference in temperature depending on where you take your temp in the area just below your tongue or if you stick it way in the back.
So what should you do? Lift your tongue up and put the thermometer in the back on the right or the left side of the membrane in the middle, the frenulum. This area is called the left or right (depending on which side) posterior sublingual pocket. Close your mouth and wait for the beep.
And that’s all there is to it 😊
You Need an Accurate Thermometer
If you’ve tried taking your temps but you’re not getting accurate results, or you want to start off on the right foot, it’s really important to get to a high quality and accurate thermometer. That means not one from the dollar store (I made that mistake!).
I recommend the Easy@Home Smart Basal Body Thermometer. It’s specifically made for keeping track of your BBT when trying to conceive, is accurate, and is Bluetooth enabled. It even sync’s up automatically with your phone.
